In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0035] The floor drain core and the floor drain of the embodiment of the present application are described below with reference to the drawings of the specification. It should be noted that the first direction is shown in the up-down direction in the drawings, and the second direction is shown in the left-right direction. Figure 3 Only the relevant cross-sectional portion of the main body 100 is shown in the cross-sectional view. Figure 3 and Figure 4 The complete ellipse 500 is shown with dashed lines.

[0036] Reference Figures 1 to 5According to the floor drain core 10 of the embodiment of the utility model, it includes a main body 100 and a cover 200. The main body 100 is provided with a flow channel 170 extending along a first direction. The main body 100 includes a water outlet 120 and a first connecting portion 110. The water outlet 120 is provided with a water outlet 121. The water outlet 121 is connected to the flow channel 170. The water outlet 121 is used to connect to the sewer pipe 30. The contour of the maximum cross-section of the water outlet 120 taken perpendicular to the first direction includes a straight edge 130 and an arc edge 140 connected end to end. The arc edge 140 is in the shape of an elliptical arc with a major axis 510 and a minor axis 520. The first connecting portion 110 is connected to one side of the second direction of the water outlet 120, and the second direction is perpendicular to the first direction. The cover sealing member 200 includes a second connecting portion 220 and a cover sealing portion 210 which are connected to each other. The second connecting portion 220 is rotatably connected to the first connecting portion 110, and the rotation axis of the first connecting portion 110 and the second connecting portion 220 is parallel to the straight edge 130. The cover sealing portion 210 is configured to conform to the water outlet 121, and the cover sealing portion 210 can open or seal the water outlet 121.

[0037] Among them, the straight edge 130 can provide space for the connection and rotation of the cover seal 200, and the arcuate edge 140 is set to the shape of an elliptical arc with a major axis 510 and a minor axis 520, so that the arc line of the water outlet 121 can be as close to the sewer pipe 30 as possible, so as to improve the space utilization rate and effectively increase the water outlet flow of the water outlet 121. Moreover, since the cover seal part 210 is arranged in the same shape as the water outlet 121, the outer contour of the cover seal part 210 is also the same as the shape of the arcuate edge 140 of the water outlet 121. For this reason, the rotation axis of the first connecting part 110 and the second connecting part 220 is set to be parallel to the straight edge 130, which can make the size of the cover seal part 210 in the rotation axis direction smaller, effectively reducing the probability of interference with the sewer pipe 30.

[0038] It can be understood that in order to ensure the water outlet capacity, the water outlet 121 will be arranged to fit as closely as possible to the outer wall of the water outlet part 120. Therefore, the projection contour of the water outlet 121 projected along the first direction onto a plane perpendicular to the first direction is the same as the contour of the maximum cross-section of the water outlet part 120 taken in the first direction perpendicular to the first direction.

[0039] Specifically, the main body 100 includes a water inlet portion connected to the water outlet portion 120, and the flow channel 170 penetrates the water inlet portion and the water outlet portion 120 along the first direction, and forms a water inlet 160 in the water inlet portion, and a water outlet 121 in the water outlet portion 120, and the water inlet 160 and the water outlet 121 are respectively located on both sides of the main body 100 in the first direction. The water inlet portion and the water outlet portion 120 can be separately provided and subsequently assembled and connected, or, in other embodiments, the water inlet portion and the water outlet portion 120 can also be integrally formed, and the water outlet portion 120 is recessed in the second direction compared to the water inlet portion to form an avoidance space 123, providing a connection space and a movement space for the cover 200. In the embodiment in which the water inlet portion and the water outlet portion 120 are integrally formed, the entire components of the main body 100 are continuous, and the portion of the water outlet portion 120 is defined as the portion of the main body 100 that can be covered by the water outlet 121 in the first direction, and specific reference can be made to Figure 1 The split position of the middle section line EE.

[0040] Reference Figure 1 and Figure 5 In some embodiments, the flow channel 170 includes a first flow channel section 171 and a second flow channel section 172 that are interconnected along a first direction. The first flow channel 170 is connected to the water inlet 160, and the second flow channel section 172 is connected to the water outlet 121. The cross-sectional area of ​​the first flow channel section 171 is greater than the cross-sectional area of ​​the second flow channel section 172. The first flow channel section 171 with a larger cross-sectional area can ensure sufficient water inflow and facilitate sewage discharge. The second flow channel section 172 with a smaller cross-sectional area can reduce the size restriction on the main body 100, ensuring that the main body 100 can form sufficient installation space and movement space for the cover 200. Among them, the cross-sectional area of ​​the first flow channel section 171 can be set to gradually decrease from the side of the water inlet 160 to the side of the water outlet 121, so as to form an inclined wall surface on the inner surface of the main body 100, reduce the probability of dirt accumulation, and guide the dirt to be discharged toward the water outlet 121, thereby enhancing the sewage discharge effect.

[0041] Reference Figures 2 to 4 In some embodiments, the length of the minor axis 520 of the elliptical arc is 2a, and the length of the major axis 510 is 2b, where a<b. The direction of the major axis 510 is perpendicular to the straight edge 130, and the maximum distance between the arc edge 140 and the straight edge 130 in the direction of the major axis 510 is h, satisfying: h>b, so as to increase the space occupation of the water outlet 121 in the sewer pipe 30 in the direction perpendicular to the first direction, so that the space occupation of the water outlet 121 is greater than the space occupation of the formed avoidance space 123, so that the cover 200 is offset installed on the floor drain core 10, ensuring the flow area of ​​the water outlet 121 and the water flow rate of the floor drain core 10. Wherein, the cross sections are intercepted along the direction perpendicular to the first direction.

[0042] Specifically, the relationship between a, b and h can be known from the ellipse equation, and the water flow area is positively correlated with the major axis 510, the minor axis 520 and the maximum spacing h of the ellipse 500 through calculation by definite integral. Among them, the maximum size of the major axis 510 of the ellipse 500 only needs to be smaller than the inner diameter W of the sewer pipe 30. The value of b is related to the interference size between the cover seal 210 and the inner wall of the sewer pipe 30. When the edge of the cover seal 210 away from the second connecting part 220 moves to the edge of the water outlet 121 close to the cover seal 200 in the first direction, the water outlet 121 has the maximum flow capacity. At this time, the interference size between the cover seal 210 and the inner wall of the sewer pipe 30 can be determined to obtain the maximum size that the minor axis 520 of the ellipse 500 can be set. Among them, it can be clearly obtained by calculation based on the definite integral that the maximum cross-sectional area of ​​the water outlet 120 when h>b is greater than the maximum cross-sectional area of ​​the water outlet when h≤b. Therefore, under the premise of ensuring the movement and installation of the cover seal 210, the maximum value of h can be obtained according to the size of the sewer pipe, and the maximum value of b can be calculated. The maximum water flow area can be calculated by comprehensively obtaining the maximum value of h, the maximum size that can be set for the ellipse minor axis 520, and the maximum size of the ellipse major axis 510.

[0043] Reference Figures 3 to 5 In some embodiments, the outer surface of the main body 100 is provided with a thread 150, and the thread 150 is used for threaded connection with the floor drain body 20, and the thread 150 has a minor diameter D, satisfying: 2b≤D. Among them, the threaded connection can quickly realize the connection between the floor drain core 10 and the floor drain body 20, which is convenient for installation and disassembly. Controlling 2b≤D can ensure that the water outlet 121 has a larger flow capacity as much as possible on the basis of ensuring the normal realization of the threaded connection. Among them, when 2b=D, the water outlet 121 can achieve the maximum flow capacity.

[0044] A sealing ring 400 may be sleeved on the end of the thread 150 away from the water outlet 121 to provide a further sealing effect after the floor drain core 10 is tightened with the floor drain body 100, thereby reducing the probability of water overflow.

[0045] Reference Figure 1 and Figure 5 In some embodiments, the opening direction of the water outlet 121 is inclined to the first direction, and the opening of the water outlet 121 is oriented toward the side close to the first connection portion 110, so that the water outlet 121 is arranged obliquely. The obliquely arranged water outlet 121 can reduce the possibility of the water outlet 121 being blocked by debris, and can reduce the rotation angle required for the cover 200 to completely cover or completely open the water outlet 121, reduce the demand for movement space, and simplify movement actions.

[0046] In some embodiments, the normal sealing of the water outlet 121 by the sealing member 200 can be achieved by applying a torsion force to the second connecting portion 220 through a torsion spring, a torquer or other device. Figure 2 and Figure 5 In some embodiments, the cover seal 200 further includes a counterweight portion 230, which is connected to the side of the second connection portion 220 facing away from the cover seal 210. By applying weight on the side of the cover seal 200 facing away from the cover seal 210 through the counterweight portion 230, a force close to the water outlet 121 can be applied to the cover seal 210 to maintain a normal cover seal on the water outlet 121, thereby achieving a sealing and odor-proof effect.

[0047] Reference Figure 2 Further, the cover seal 200 further includes a counterweight 240, the counterweight portion 230 includes a counterweight seat 231 and a cover 233, the counterweight seat 231 and the cover 233 are detachably connected, the counterweight seat 231 is provided with a receiving cavity 232, the cover 233 can close or open the receiving cavity 232, and the receiving cavity 232 is used to receive the counterweight 240. By adjusting the number or weight of the counterweight 240, the driving force required to drive the cover seal 210 to expose the water outlet 121 can be adjusted to adapt to different drainage conditions.

[0048] Reference Figure 2 In some embodiments, the floor drain core 10 further includes a sealing member 211, which is disposed on the side of the cover seal 210 facing the water outlet 121. The sealing member 211 is used to abut against the water outlet 120 to improve the sealing performance when the cover seal 210 seals the water outlet 121, and reduce the probability of odor transfer to the sewer. Among them, a boss 212 can be provided on the cover seal 210, and the boss 212 can be penetrated through the water outlet 121. The sealing member 211 is disposed around the boss 212 to abut against the cover seal 210 at the edge of the water outlet 121, thereby achieving a good sealing effect. The sealing member 211 can be connected to the cover seal 210 by bonding or pre-tightening with a pre-tightening member, or can be integrally formed with the cover seal 210 by means of glue injection or the like.

[0049] Reference Figure 2 and Figure 5 In some embodiments, the floor drain core 10 also includes a lifting member 300, and a third connecting portion 180 is provided on the side of the main body 100 away from the water outlet 121. The lifting member 300 is rotatably connected to the third connecting portion 180. The lifting member 300 can provide a force structure for the user, which is convenient for the user to install or disassemble the floor drain core 10, and the lifting member 300 can rotate relative to the main body 100, which is convenient for storing the lifting member 300 and reducing the probability of the lifting member 300 hooking dirt.

[0050] Furthermore, a trough 190 is provided on the side of the main body 100 away from the water outlet 121, and the trough 190 is connected to the flow channel 170. The trough 190 is formed with a trough bottom 191 on the main body 100, and the third connecting part 180 is located in the trough 190. The pulling member 300 can move at least a part to fit the trough bottom 191. The setting of the trough 190 can further accommodate the pulling member 300, so that the pulling member 300 can fit into the main body 100, further reducing the probability of the pulling member 300 hooking dirt, reducing the probability of the floor drain being blocked, and ensuring the drainage effect.

[0051] Reference Figure 5 According to the floor drain of the embodiment of the utility model, it includes a floor drain body 20 and a floor drain core 10 of any of the above embodiments, the floor drain body 20 is used to be fixed to the ground, and the floor drain core 10 is connected to the floor drain body 20.
